Barkhausen Noise and Critical Scaling in the Demagnetization Curve
, 2002 The demagnetization curve, or initial magnetization curve, is studied by examining the embedded Barkhausen noise using the non-equilibrium, zero temperature random-field Ising model.

Effect of Measurement Conditions on Barkhausen Noise Parameters
Advances in Electrical and Electronic Engineering, 2008 The Barkhausen noise was measured in plastically deformed low-carbon steel at various measurement conditions. Strip samples magnetized by a single yoke were used for investigation.

Statistics of Avalanches with Relaxation, and Barkhausen Noise: A Solvable Model
, 2013 We study a generalization of the Alessandro-Beatrice-Bertotti-Montorsi (ABBM) model of a particle in a Brownian force landscape, including retardation effects.

Hysteresis and Noise in Stripe and Clump Forming Systems
, 2005 We use simulations to examine hysteresis and noise in a model system that produces heterogeneous orderings including stripe and clump phases. In the presence of a disordered substrate, these heterogeneous phases exhibit 1/f$^\alpha$ noise and hysteresis ...

Application of flaw detection methods for detection of fatigue processes in low-alloyed steel [PDF]
Transport Problems, 2007 The paper presents the investigations conducted in the Fraunhofer Institute (IZFP Saarbrücken) by use of a BEMI microscope (BEMI= Barkhausenrausch- und Wirbelstrom-Mikroskopie or Barkhausen Noise and Eddy Current Microscopy). The ability to detect cyclic

, 2017 Current terrestrial gravitational-wave detectors operate at frequencies above 10 Hz. There is strong astrophysical motivation to construct low-frequency gravitational-wave detectors capable of observing 10 mHz - 10Hz signals.

Magnetization fluctuations and magnetic after-effect probed via the anomalous Hall effect
Physical Review ResearchTaking advantage of the anomalous Hall effect, we electrically probe low-frequency magnetization fluctuations at room temperature in a thin ferromagnetic Pt/Co/AlO_{x} layer stack with perpendicular magnetic anisotropy. We observe a strong enhancement of

Beyond power laws: Universality in the average avalanche shape
, 2010 We report the measurement of multivariable scaling functions for the temporal average shape of Barkhausen noise avalanches, and show that they are consistent with the predictions of simple mean-field theories.
